1 Claim. (Cl. 206-46) This invention relates to a new and improvedshockproof package.

It has heretofore been proposed to provide a package in which afrangible article is held in a plastic tube, which is twisted tightabove and below the article, strains being taken by the resiliency ofthe plastic tube.

It is an object of this invention to provide a package of the generalcharacter above described, which will be simpler and cheaper inconstruction, and more rigid in use. The invention accordingly comprisesthe articles hereinafter described and shown in the accompanyingdrawings, in which:

Fig. 1 is an exploded view;

Fig. 2 is a section of the line 2-2 of Fig. 3;

Fig. 3 is a section of the line 33 of Fig. 2;

As herein illustrated, the outer casing may be a cylindrical tube offiber-board, which may be closed at each end by a cap 12. A plastic tube13 which may be of a somewhat smaller diameter than the casing 10, haseach end wrapped around and attached to a separate ring 14, 14a of asize to fit within casing 10.

This plastic tube is somewhat longer than the casing 10 as will behereinafter understood. Within the casing 10 there is carried apolygonal frame, or tube, 15 of a size to fit snugly within the casing10, and one side of this casing may be slit as shown at 16, so that itmay be shipped and handled as a flat sheet.

The device is assembled by inserting the bottom ring 14 with the plastictube attached, within the casing 10. The polygonal frame 15 is thenfolded about the plastic tube above the bottom ring and it is presseddown inside "ice the casing 10. The top ring 14a may now be turned untilthe plastic tube is brought together near the bottom to close it by thetwist, as shown at 17 in Fig. 3. The package is now in position toreceive the article to be packed above the twist. Thereafter the ring 14may be inserted into the top of the casing above the top of frame 15 andtwisted until the plastic tube is brought together also above thearticle, as shown at 18. This twisting is continued until the tube isbrought under tension. It will be seen that the polygonal frame 15serves to hold the rings 14 and 14a spaced from each other, and hence tomaintain the tube under the tension resulting from the twisting. Theparts are retained by friction to prevent the untwisting of the tube.The caps 11 and 12 may be then inserted over the tube, and it is readyfor shipping.

From the above construction, it will be seen that all parts of thiscontainer may be made from standard parts without special forming, andhence the package itself may be made with a minimum of expense.

What I claim is:

A shock-proof container comprising a tubular member of polygonal crosssection, a pair of rings having approximately the same diameter as saidtubular member and each rotatably supported on an end of said member, aplastic tube member within said polygonal member having its endsextending through and down over the outside of said rings and securedthereto, the plastic tube being adapted to contain an article and beingof a length to permit it being twisted together above and below thearticle thereby to enclose and support the same, an outer casing forsupporting and holding said members in alignment, and means :closingeach end of the casing.
